Would be interesting to compare leela (with different networks) to all the other usual AB engines My impression - not sure if that's true or not, so I'd like to see it tested - is that SF10's play is more similar to LC0 than e.g. SF9 was. That would make sense because if LC0's style is the "chess t...

One billion random games by Steven Edwards: http://www.talkchess.com/forum3/viewtopic.php?t=40193

Looks like a lottery. Quite the contrary: the list appears to be remarkably well-corelated with playing strength. The above-mentioned German-language article says "surprisingly accurate" ( überraschend genau ), and personally I cannot but agree. Frankly, I thought such tests are outdated now, but c...

If I try to host the GPU out of the box using a raiser card adopter something like shown below, will it affect the performance? The idea is to give the gpu more cooler air to breath & to cool down. Additional case fans may be a better solution. It is basically the same idea: help the GPU fan by not...

I downloaded the latest Lc0 about a week ago on my laptop (with GPU 1060), and looked at its analysis (infinite mode) on lots of positions. Typically, in the opening evals are roughly double what they should be; in general a clean pawn up shows as about two pawns. However, the initial position with...

Transitivity is pretty well obeyed by regular engines, I even came to pretty conclusive results that on large Elo spans it obeys the logistic and not Gaussian distribution. Some 2-3 years ago this was unclear to me. I am not sure what you mean by "ratings in engine-to-engine Elo lists get compresse...

I was hoping someone would come up with an alternative, two-parameter Elo model able to describe Leela's performance... But, aren't all engines schizophrenic to a degree? :-) We already know that engine-to-engine games expose a weakness of the Elo model - namely, it assumes a fixed transitivity form...

Suppose TCEC had a rule that after the tournament is finished, each engine is awarded random bonus points. For all engines the bonus points are drawn from the same random distribution, so this is absolutely and completely fair. But clearly this would just add noise to the tournament results, distor...

The inclusion of games of a randomly crashing engine clearly hurts fairness. How can one hurt fairness by including non-crashing games of a crashing engine? On the contrary, it is their removal that hurts fairness. If it's unfair for an engine to receive a point just because its opponent crashed, i...

Imagine a Stockfish version with a particularly nasty bug that causes it to crash after capturing a knight on f4. This scenario will occur infrequently, but will cause SF to lose the game on the spot. A tournament in which this happens in, say 6 games out of 30, will lead to a distorted view of the...
